The console is constructed using extruded aluminium beams, steel panels and 3mm thick metal side plates to ensure rigidity and mechanical reliability on the road, as well as easy flightcasing. Individual circuit assemblies are accessible by removal of the steel base. A durable but soft front armrest is provided for comfort. Front, top and rear write-on strips are provided for channel marking. High quality proven reliable parts are used throughout. High performance op-amp and discrete circuits are used to ensure low noise and sonic purity. The GL4000 reflects our commitment to providing the best audio mixing solutions and customer support.

Sadly Allen & Heath don't see fit to store any decent information on their older products besides the manual and a few low-res brochers. If you use or have used this mixer, please add some uder feeback or comments below!
